BTC is not doing so well lately.
Directly or indirectly, altcoins are affected too.
Nevertheless, is the downfall of Bitcoin makes any good to altcoins?
There is gradually improvement. At least, we are having some percentage increase for the past 2-3 days now.
Most of the time, if btc plummets, since most altcoins are paired with it, they also have every tendency to fall along with it. Although, there are some altcoins that, despite falling with btc, a some points, they may begin to rise, irrespective of the price of btc at that moment.
